X brings back Voice Notes to X Chat
Posting Voice Notes publicly on X may no longer be possible, but you can now share audio messages within X’s direct messaging system, X Chat, once again. The social network announced late on Wednesday that support for Voice Notes is now available within its private messaging service.
The feature, which works in both one-on-one messages and group chats, is activated with a push of the voice input icon to the right of the chat’s text box. At launch, you have to continue to press the button to record the voice message, but we found that a press-and-hold gesture followed by a swipe up allows it to record without having to keep your finger on the button.
The new addition could make X Chat more competitive with other messaging apps, where recording audio voice notes has long been a standard option. This is particularly important to the company, given the recent spinout of X Chat as its own stand-alone app.
It could also assuage angry users who didn’t appreciate that the upgrade to X Chat removed the Voice Notes feature.
The move follows X’s recent beta tests of an X Chat app on iOS, which offers access to X’s upgraded DM feature. While the company claims that chats are end-to-end encrypted, security experts have warned that the service is less secure than other encrypted messaging apps, like Signal.
The introduction of the new app reflects a strategy change for the social network, as owner Elon Musk once said X would become an all-in-one super app, or “everything app.” Now, the company is looking to make pieces of its app available as their own experiences. X Money, X’s payments service, is also being tested as a separate app, for instance.
Voice Notes have been on X Chat’s roadmap for some time despite their temporary removal. When X first introduced its new chat platform in November, it said the audio feature would be “returning soon.”
Currently, the X Chat service also supports other features, like the ability to edit and delete messages, block or get notified of screenshots, share files, make voice and video calls, and set messages to automatically disappear.

Why Andrew Yang is building instead of waiting for Washington
Andrew Yang’s 2020 presidential campaign was based on a warning that automation and AI would hollow out the labor market and concentrate wealth in the hands of a few. At the time, ideas like Universal Basic Income felt fringe. Now Dario Amodei, Sam Altman, and Bernie Sanders are all saying versions of the same thing.
An entrepreneur at heart, Yang has found a new way to put money back into the hands of the people — one phone bill at a time. On this episode of TechCrunch’s Equity podcast, Rebecca Bellan talks to Yang about his startup Noble Mobile, which pays you to use your phone less, ways to combat the “attention economy,” and what startups can do when the government won’t move.

xAI fired an engineer who raised alarms about Grok safety, new lawsuit claims
A former engineer at Elon Musk’s xAI has filed suit against the company and its parent SpaceX claiming he was fired for raising concerns about AI safety.
Devin Kim, who left xAI in September 2025, filed the suit in a California state court on Tuesday. The complaint comes days before SpaceX is set to join the public markets in what’s shaping up to be the largest IPO in history.
According to the lawsuit, which TechCrunch has viewed, Kim became a prominent voice for AI safety while working on Grok, xAI’s AI chatbot. He allegedly complained repeatedly about xAI’s failure to prioritize safety in Grok’s development, a product that has since come under fire for a range of safety and behavioral issues. In particular, Kim was concerned with the possibility that Grok could foment discrimination and help spread information about weapons of mass destruction.
“Grok, of course, proved Mr. Kim right by engaging in spectacular displays of online hatred and vitriol, with the model likening itself to Hitler (‘MechaHitler’),” the lawsuit reads. “Following the Hitler debacle, Mr. Kim worked to re-evaluate Grok’s political bias and discriminatory tendencies.”
A few months after Kim departed xAI, Grok made headlines again when the chatbot was used to flood X — Musk’s social media platform that also falls under the xAI umbrella — with nonconsensual sexual imagery.
The lawsuit also positions Kim as a whistleblower who was concerned about xAI’s alleged disregard for AI safety as “unlawful” in areas such as internet regulation, consumer protection and unfair business practices, and arms and explosives regulation, among others.
xAI and SpaceX did not immediately respond to requests for comment.
Kim’s focus on AI safety predates his time at xAI. While working at Scale AI, Kim worked on early safety AI initiatives, like leading a project that produced training data for AI to train systems to detect harmful content and comply with governance policies. Last week, the nonprofit Center for AI Safety, which focuses on AI risks, named Kim as its president.
Interestingly, the lawsuit doesn’t implicate Musk himself as a reason for a lack of safety. Rather, Kim’s lawyers describe Musk as having directed xAI to follow the law and implement appropriate safety and testing processes. Instead the claim targets Kim’s supervisor, xAI co-founder Jimmy Ba — who left the company earlier this year — saying that Ba ignored Musk’s directives and retaliated against Kim for pushing for safeguards, in an effort to “silence his repeated complaints about AI safety and biases.”
The lawsuit portrays Ba as someone who vehemently opposed AI safety measures, allegedly telling Kim at one point “AI will kill us all anyway,” and who was instead driven by a mission to make xAI the first to reach superintelligence.
“In one instance in or around August 2025, Mr. Ba attempted to thwart EU safety regulations during the release of Grok Code 1, misrepresenting aspects of the model in order to avoid legally required testing,” the complaint says. “Mr. Ba indicated that he would rather release an unsafe model than a poor-performing one. Mr. Musk ultimately had to intervene.”
According to the lawsuit, Kim intended to give a presentation of his findings the week of September 15, 2025, but Ba called him into a meeting and told him they should “go [their] separate ways” without providing a satisfactory reason.
TechCrunch has reached out to Ba for comment.
Kim is seeking compensatory and punitive damages, as well as a declaratory judgment that xAI and SpaceX’s conduct was unlawful.

Anthropic’s Dario Amodei has just one direct report
If founders and other business leaders weren’t already envious of Dario Amodei, who sits atop one of the world’s fastest-growing AI companies — currently valued by private market investors at roughly the trillion-dollar mark little more than five years after it was founded — they’re going to be seriously envious now.
In a new sit-down with Bloomberg’s Emily Chang, he reveals he has just one direct report; that’s his chief of staff. Everyone else on Anthropic’s executive team reports to his sister, co-founder and President Daniela Amodei, who handles day-to-day operations.
Anyone who has managed a large team knows that the people side of the job has a way of consuming everything else. Amodei’s arrangement frees him to focus almost entirely on strategy, culture, research direction, and sweeping essays on the future of civilization (with footnotes). “It’s incredibly freeing,” he tells Chang.
It’s a highly unusual structure. OpenAI’s Sam Altman reportedly has around half a dozen direct reports, which is far more standard, while Nvidia’s Jensen Huang — another extreme outlier — has many dozens.
